I'm taking my first trip to Europe from the US via Icelandair and will be taking a large backpack (internal frame, checked bag) rather than a suitcase. On the Icelandair website they state:
Backpacks and other luggage with loos straps and items attached on the outside of check baggage need to be wrapped in clear thick plastic bag. Proper clear thick plastic bags are available for sale at most of our departing stations.
*loose. This message appears when selecting "Backpacks" from the "Sports Equipment or Odd Size Baggage" dropdown.
I've never traveled with a backpack that wasn't just a carry-on before. I obviously get why something like this needs to be bagged, but my question is what sort of bags are allowable for this (apart from them being clear of course)? Do they need to be a certain material? I realize I can probably buy one at the airport, but if they charge an arm and a leg for it I would like to find a cheaper alternative and bring my own if possible.
Alternatively, how much should I actually expect to pay for one, if I end up needing to buy one at the airport?
